Part Number: ADS1148 Hello, I'm facing a problem with the internal reference. After many trial and errors my Read value was still maximized and noticed that there is no output Reference Voltage between VREFOUT and VREFCOM. Tried all settings and it worked only when using "Internal reference selected and internally connected to REFP0 and REFN0 input pins" this setting in the MUX1 register, but it's not good for me because I'm planning on using 2 Wire RTD measurements and we have a Reference resistor on REFP0 and REFN0. I've got to a point where I'm thinking it's related to some silicon problem... The software I've done it based on the recommended pseudo code. (+ tried all variation, even those which are on the forum). Maybe I'm still missing something... The ID from IDAC0 Control Register is 9(Full value of register is 0x90), maybe it helps. Attaching the schematic also. Thank you. Balazs
